I am looking a a 328i BMW convertible and i am having a really hard time deciding weather or not to buy this car i have one main concern. This is about the run flat tires are they really bad i want this car a lot and i don't know if it is a deal breaker I have heard that the price is insane and they don't last long at all i called my BMW dealer and was told there was a tire warranty i haven't been quoted yet but was wondering if anyone has had a problem with the warranty i have heard if the tires are changed it voids the car warranty and if there is uneven where it voids the tire warranty my questions are is the tire warranty worth the money. if you void the tire warranty can u buy new tires and a new warranty and start over. i am a commuter and i live in the burbs and drive 25 minutes to work everyday will the tires be a problem i am not planing on racing this car just for enjoyment and my final question is BMW an easy company to get along with i am referring to have they denied people of there warranty or have been a pain in the butt thank you for your info!
